读取联系人信息

Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, 

    null,
null, null, null); 

  while
(cursor.moveToNext()) { 

   String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); 

   String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 

  

   Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 

        null, 

        ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+" = "+ contactId, 

        null,
null); 

    while
(phones.moveToNext()) { 

     String phoneNumber = phones.getString(phones.getColumnIndex( 

         ContactsContract.CommonDataKinds.Phone.NUMBER)); 

     Log.i("RongActivity",
"phoneNumber="+phoneNumber);

    } 

    phones.close(); 

  

    Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, 

       null, 

       ContactsContract.CommonDataKinds.Email.CONTACT_ID
+ " = " + contactId, 

       null,
null); 

       while
(emails.moveToNext()) { 

        // This would allow you get several email addresses 

        String emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));

        Log.i("RongActivity",
"emailAddress="+ emailAddress);

       } 

       emails.close();
